Deep Groove Ball Bearing 6400 Series
Bearing Introduction Of Deep Groove Ball Bearing 6400 Series
The deep groove ball bearing 6400 series is the most commonly used rolling bearing. Its structure is simple and easy to use. It is mainly used to bear radial load, but when it increases the radial clearance of the bearing, it has certain angular contact ball bearing performance and can withstand combined radial and axial loads. It can also be used to withstand pure axial loads when the rotational speed is high and thrust ball bearings are not suitable. Compared with other types of bearings of the same size as deep groove ball bearings, these bearings have a small coefficient of friction and a high limit speed. However, it is not resistant to impact and is not suitable for heavy loads.
